the largest unknown in the whole process seemed to be the air leakage characteristics of the existing windows. the windows were clearly pretty leaky, and we knew that air leakage would be an important factor in energy use, so we decided to test a sample of windows.air flow measurementour windows air flow measurement apparatus included a sheet of clear acrylic designed to fit over the window to be tested, and taped in place to create an airtight chamber. (we had four of these sheets cut to fit different-sized windows.) a fan was connected with rigid pvc pipe and flexible tubing to a fitting in the acrylic, az allowing depressurization of the inside arizona surface replacement of the window. measurement of the pressure drop across an orifice in

the test results quantified leakage that residents have long known about from experience. measured leakage interpolated to a windows pressure az difference of 75 pa, arizona and replacement ranged from 9 to 96 cfm. the median value for the windows most common window size was 44.1 cfm at 75 pa, or 2.42 cfm per linear ft of perimeter crack (see figure 1). calculated at a pressure difference of 50 pa, the median leakage value az is 35.6 cfm, and at 4 pa, 9.3 arizona and replacement cfm. (one standard pressure difference windows and az used in window testing is 75 pa; 50 pa is common arizona in building studies; replacement and 4 pa is used to approximate windows average operating conditions.)
